Kingdoms of Life Essay

On our satellite earth we have what argon call(a)ed lands, 5 to be exact, consisting of a very various(a) host of musical accompaniment things. Using these five virtually kingdoms we classify our species and organize information on what we be and what resides with us. When we place ever soy backing creature into wizard of the five kingdoms it disclose helps us understand the world more or less us and its habitants. The five kingdoms take on moneron, Protist, fungus kingdom, Plantae, and the one we call home, Animalia.1. Monera The simplest of all organisms is the bacterium of the Moneran kingdom. They ar disturbed d take into two types true bacterium and Archaebacteria. Eubacteria is know as the true bacteria which makes up the roughly 10,000 species in the Moneran group. Archaebacteria or antiquated bacteria if you will, is the minority of the group and argon sole(prenominal) found in extreme environments including solely non limiting swamps, salt lakes, deep-o cean hydr early(a)mal vent, etcetera at that place argon many types of species belong to the Moneran kingdom that have moreover to be detect. Monerans be also the still group within the five kingdoms that argon all prokaryotes. Prokaryotes are one- cellphoneed or colony of cells.2. division Protista In this kingdom we have multi cellular organisms (Protista) which are non a part of nor do they fit, the Animal, Plant, or Fungus body politic. In the beginning, protozoa were placed in a sub-kingdom of Animalia scarce because of the problems this sorting had, it later became its own kingdom. any members of this phylum have what are known as nucleated cells and live in aquatic habitats (both freshwater and marine). According to Lynn Margulis, K.V. Schwartz and M. Dolan (1994), the cells of all kingdom Protoctista originally formed by bacterial symbioses or symbiogenesis. Members of this kingdom are not considered sentient beings because they do not come from an embryo, they a re not plants nor are they considered fungi because they do not develop from spores.3. kingdom Fungi There are some members of the state Fungi that are associated with algal cells of the nation Protista and/or prokaryotic cyanobacteria of the Kingdom Monera. Fungi plays a very detailed role in natures continuous rebirth Fungi truly recycle all dead native matter turning it into useful nutrients. Fungi consits of species like mushrooms, molds, mildews, stinkhorns, rusts, puffballs and many others. There are on estimate 100,000 known species today with hundreds of new species being discovered each(prenominal) year.4. PlantaeWith over 1.6 million species of living organisms on earth and new species discovered every single day, in contingent insects and nematodes residing in rsecluded equatorial regions. However, with the present send of destruction, a majority of the virgin tropical rain forest are headed straightaway for extinction, leaving millions of species undiscove red by the homosexual race. It is the theory that approximately 99 percentage of species that ever resided on earth were extinct long before the human ever set foot on this planet. take down with humans having such an incredible importation to the development of earth, technically they are considered to be newcomers on this marvelous planet. If all theories are correct, earth is aged at intimately 4.5 one million million million years old, meaning the ancient life forms (such as the cyanobacteria) appeared roughly 2-3 billion years ago. 5. AnimaliaThere are nine phyla of this kingdom including the following phylum Porifera (poriferans), Cnidaria (cnidarians), Platyhelminthes (flatworms), Nematoda (roundworms), phylum Annelida (annelids), Mollusca (molluscs), Arthropoda (arthropods), Echinodermata (echinoderms) and phylum Chordata (chordates). Animals are considered to be part of this group because they are all multi-cellular organisms whose cells are connected by a plasma tis sue layer and not by a cell wall of cellulose like the others.The differences mingled with plants and animals conduct to the division of all life into what is known as (referenced above) Plantae and Animalia. In animals, the cells are organized into tissues and specialized tissue systems that stomach them to move freely in bet of food. They build energy by acquiring and ingesting their food, unlike plants, which use the system photosynthesis to avail from the nutrients they need to survive. A well positive nervous system with sensory and travel nerves is what enables animals to receive environmental stimuli as well as a result to the environment around them. It was found that some were plant like mend others (protozoa) resembled animals in that they obtain locomotion by instrument of flagella and that they actually digest food.The Animal Kingdom holds the most species of all of the kingdoms, ringing in a little over one million. Interesting fact, is that more than half of the animal species are insects. The result of 300,000 beetles plus the 800,000 dissimilar insect species a make up the largest order of insects (one fifth of all species utilize a total of 1.5 million). It has been said that if the species amongst plants and animals on earth were lined up at random, every 5th species would be a beetle.VirusesViruses are out of the Kingdom assortment completely and sometimes they are said even to belong to their own kingdom, the kingdom Virus. The small and less entangled infectious agent is made of tiny macromolecular units composed of DNA or RNA covered by an outer(prenominal) protein coat. Virus do not call for membrane-bound organelles, ribosomes, a cytoplasm, or any other source of energy formation of their own. They do not have the self-maintenance metabolic reactions of living systems, they lack cellular respiration and virgule exchanges. They are completely capable of reproducing but solitary(prenominal) at the expense of a host cell. They can and will only survive as minute macromolecular particles outside of their body. Plant viruses are transferred between each other by insects that operate on sap, such as aphids, while animal viruses can be carried by blood-sucking insects (mosquitos for instance).http//www.biology-questions-and-answers.com/life-kingdoms.html
